The present invention provides a method for forming a naked collation package. The method comprises the steps of: a) providing orderly arranged packages independently packaged by film materials; b) providing a bare finishing film; c) arranging the individually packaged packages in an ordered arrangement; d) arranging the bare collation film so as to at least partially wrap around the ordered arrangement of individually packaged packages without having to contact the ordered arrangement of individually packaged packages; and e) performing heat shrinking the bare finishing film by exposing it toheat shrinking conditions such that the bare finishing film shrinks and tightly wraps the neatly arranged packages without sealing the packages. The present invention further discloses packages packaged with bare trim films.
